We use Bitbucket as primary host for open source projects to avoid fragmenting access control. Proposal repositories need to be private and most coauthors prefer journal article repositories to be private. GitHub's pricing model would encourage us to consolidate these private repos, but each has a small number of different external collaborators, so that would yield undesirable granularity. Meanwhile, all of our software products are open source, with a much larger group of contributors than the union of the proposals/papers. We mirror the flagship project on GitHub, but all of our development is on Bitbucket.
